Members of Congress represent the people of their district in the United States Congress by holding hearings, as well as developing and voting on legislation. All bills must pass Congress before they can go to the President to be signed into law.
A special feature of the sarcolemma is that it invaginates into the cytoplasm of the muscle cell, forming membranous tubules radially and longitudinally within the fiber called transverse tubules (T-tubules).t each end of the muscle fiber, the surface layer of the sarcolemma fuses with a tendon fiber, and the tendon fibers in turn collect into bundles to form the muscle tendons that then adhere onto bones.
The minireview in this and the following issues updates our understanding of the structure and function of the basement membrane, cytoskeletal costameres, and the major trans-sarcolemma links (integrins and dystroglycan) in skeletal muscle. The basement membrane surrounds skeletal muscle fibers and is now known to be critical in muscle fiber structure and function. The skeletal muscle basement membrane is composed of the basal lamina and the reticular lamina. Basal lamina is directly linked to the sarcolemma.
